To all whom it may concern:

Be it known that I, CARLn'roN ELLIS, a citizen of the United States, anda resident of Montclai-r, in the county of Essex and State of NewJersey, have invented certain new and useful Improvements in Compositionof Matter Adapted for Use as Disinfecting Solutions, 620., of which thefollowing is a specification.

This invention relates to a disinfectant and insecticidal composition orsolution and in one phase relates particularly to a mix-. ture ofchlorinated hydrocarbons. For the base solvent or vehicle I prefer touse chlorinated aromatic hydrocarbons such as chlorbenzol, chlortoluol,chlorxylol and chlorinated solvent naphtha. Ordinary monochlorbenzol iswell suited for the purpose and it is used herein as anillustrativevehicle. a

A certain quantity of carbolic acid or such as cresylic acid is, in somecases, incor orated with the chlorinated hydrocarbons. referably a muchsmaller amount of the carbolic acid is used than chlorbenzol, usuallyonly one-fourth to one-sixth as much.

In this composition, I also preferably use a small amount of a lightvolatile chlorinated hydrocarbon of the aliphatic series, carbontetrachlorid being suitable for the purpose, but other chlorinatedcompounds such as chlorinated acetylene, dichlorethylene,trichlorethylene and the corresponding chlor compounds of ethance,including the higher chlorinated compounds thereof may be employed.Carbon tetrachlorid has a tendency to make the composition acid in thepresence of moisture and when it is used the solution should be made asnearly 'anhydrous as possible in case the composition is to be put up intin cans.

Other bodies which have a disinfecting or insecticidal action are thedichlor and trichlorbenzols and similar chlorinated derivatives. Of theother aromatic hydrocarbons, paradichlorbenzol is excellent for thepurpose and may be added as desired, or, say to the extent of five orten per cent. Other bodies which may be added are pine oil, Russianturpentine, wood tar oil and the like.

The composition has the advantage over many of the preparations now'onthe market of being substantially free from readily in flammablecomponents. While gasolene is often used as a vehicle for variousinsecticidal bodies it is highly inflammable. The same criticism appliesto carbonbisulfid, the vapors of which are extremely inflammable. In thepresent case by using chlorbenzol or similar chlorinated body as thebasis and especially by adding small amounts of carbon tetrachlorid orsimilar chlorinated body, a substantially non-inflammable product may beobtained,.one for example, which cannot be ignited readily by bringing alighted match in contact with the solution.

While I may proportion the chlorinated aromatic hydrocarbons and thechlorinated aliphatic hydrocarbons in various ways, I

prefer a ratio in the specific case employed herein of chlorbenzol about7 parts and carbon tetrachlorid 1 part by volume. This gives a vehicleof excellent non-flashing qualities having good solvent power so that itwill take up quantities of dichlorbenzol, carbolic acid and the like asmay be required in preparing the disinfectant composition.

Another formula containing carbolic acid is prepared frommonochlorbenzol 70 parts by volume, carbon tetrachlorid 10 parts byvolume and carbolic acid crystals approximately 15 parts by volume(measuring the carbolic acid in a molten state.) These proportions maybe increased or decreased according to circumstances, each componentbeing varied more or less. Preferably, however, the chlorbenzol oraromatic chlorinated compound is largely in excess of the carbontetrachlorid and also of the carbolieacid when the latter is used.

Ordinary chlorbenzol is fairly difficult to ignite when it is wellpurified and free from benzol and toluol. For example, when a lightedmatch is brought in contact with a thin layer, it does not inflamequickly but only after the surface has become heated to a considerableextent does flashing and burning take place. Since this degree ofinfiarnmability is objectionable for some purposes, a relatively smallamount of carbon tetrachlorid may be added to produce" a vehicle whichdoes not flash or burn in this manner and I have observed thatapproximately one part of the tetrachlorid to seven parts by volume ofthe chlorbenzol makes an excellent proportion. As stated, carbolicploying at least five or ten per cent. and upward to twenty-five percent. or more of the,

. say to the extent of five phenol in the composition.

As stated, other bodies such as pine oil, er cent, or more, Russianturpentine in li e amount, highly purified wood tar oil, especially thathaving a high boiling point and heavy oil of acetone obtained in themanufacture of ordinary acetone may be used in small amount.

'It is also possible to add other material such as a small amount oflaundry soap which may be dried for the purpose and dissolved in thevehicle by heating. In this manner an anhydrous composition is obtained, if desired, in which carbon tetrachlorid maybe used withoutdanger of free acid being developed. Of course, it is possible to usecompositions containing water such as ordinary sodium oleateinconcentratedform but preferably I employ an anhydrous or substantiallyanhydrous compo sition. A composition containing moisture has oneadvantage,

disinfecting solution is added to water, an emulslon is readily obtainedby means of which the composition may be readily dis-' surface orsprayed in tributed over large suitable atomizing apparatus and thelike.

l. A composition of'matter which may be used as a, disinfectingcomposition, which comprises carbolic acid incorporated in a vehiclecontaining a major proportion of a chlorinated liquid hydrocarbon of theben- 201 series and a minor proportion of carbon tetrachlorid.

2. A composition of matter which ma be used as a disinfectingcomposition W 1lCl1 comprises a phenol dissolved in a vehicle consistinglargely of chlorbenzol and a substantially lesser proportion of lightvolatile chlorinated compound of the aliphatic series.

composltion comprising approximately monochlor benzol 7 0 parts byvolume, carbon tetrachlorid 10 parts and phenol 15 parts,
